Air con in Perth Metro…

Try Airconditioning Solutions 93981777. I found them to be very helpful in advisng the right system for our situation ie: we’re on water tanks, are few degress higher than metro in summer and have frost in winter. The consultant we had was Tony Ryan and from emroy I seem to think he might live up that way.

Others ones I faxed for quotes at the time didn’t even bother to come out to the house to look at what we were trying to aircondition!

Good Luck whatever you decide.

OMG !!!
Don’t do it Wayne !!
You’re adding one more air cond that Western Power can’t cope with before summer.
Blackouts in Feb for sure.
And with a state election due around the same time, your air cond could be the straw that breaks the camels back, and causes a change of govt..can you live with that on your conscience ???

Hi Wayne

The difference between Evapoative and Refrigerated A/C is:

1) Evap A/C adds moisture to the air.(making the air muggy but cool), Less mechanical parts to ware out, but will require more maintenance (cleaning of the water resevior and pump) and will require water (like a toilet cistern) it adds water when level drops, they can be noisey (To neighbours)and usually is ducted throughout house (more instal costs) They are mounted on the roof of the house and will require tiles to be removed (possible water leaks from rain) and

2) Refrigerated takes moisture from the air. (making the air dry) Has more mechanical parts but with technology today are quite reliable and are super quiet. They can be ducted throughout but are generally Split Systems which has less install costs as they are hung on a wall with a hole drilled through the wall for the conecting pipes, drain and wiring, with the outdoor unit mounted on the ground.

With both systems you might require the services of an electrician as well if the A/C company do not have a qualified electrician. Check their quote to be sure.

Hope this is of some help.

Hi thecrest

Slit systems are good in terms of energy consumption. Diakin have a new model out which is inverter driven ie: compressor speeds up when heating/cooling is required and slows down as it reaches the temp set point (saving power consumption). Older units just turn on and off as required.(exactly the same as your fridge)

My personal opinion is Daikin is a far superior brand in quality and performance. Other good brands are LG and Mitsubishi.

Although there are much cheaper makes available the quality will be much less and will last a great deal less costing much more than the initial savings to repair or even replace a few years later.

There is even a gas system (same gas as in your kitchen) which runs the heating side of things which is incorporated into the ducting on ducted units which might save you heating costs in the long term but these might be quite costly up front. I have not had any experience working on/with these units but thought they worth looking into though.

Dear wayne,With the limited experience I have had with Air-con in the Perth environs I would suggest orientating toward re-frig,this method can cool/heat quickly thus can be set 1/2 hr. before arriving home so is not in use during time not in the residence, also allows for year round use.Evap. is great for summer given you have doors/windows left open for airflow and the weather is not humid as this significantly reduces its effectiveness (as some one pointed out earlier you can switch off the water and use fan only for cooling)Evap. are ideal in a commercial situation where you have constant foot traffic in and out of the building and in fact are cheaper to run than refrig.in that situation.As you are doing it for the tenant you are not having to pay the costs of running (wear and tear excepted)and you are providing them with an all year round temperature control.One other consideration with Evap. is if the airflow is inadequate it can result in development of mould and mildew inside the building(paint cupboards clothes etc.)I hope this helps in your thoughts.Regards Mitchell.

Wayne, unsure on any install. costs,quotes probably best way for market/average price make sure however that comparision is same i.e apples for apples.,get breakdown on all aspects labour, unit, power etc. My understanding is initially Evap is cheaper to purchase.Another thought is if a number of other people are looking at buying to join up to secure a better deal.Regards Mitchell.

Hi Wayne

As a qualified Refrigeration / Airconditioning Mechanic although not working in the field at present.The indoor unit is hung on an external wall as preference to the installer (easy install).

They can be hung on an internal wall also. Although you will have to run the pipe work up into the ceiling then out through the eves to the condensing unit (outdoor unit). The piping can be hidden inside trunking, usually about 300-350mm long. The total pipe run should not exceed 15meters from inside to outside or more refigerant would be required.(more costs)

You can even get units that allow up to 4 indoor units run from 1 outdoor unit. These are good if you want to add indoor units to other rooms at a later date or when funds are available. Remember each pipe run has max 15 meters, so central location of outdoor unit should be taken into consideration.
